Abstract

A structure 100 according to an embodiment of the present disclosure includes: a vibration part 110 configured to hold a vibrating member; a housing 120 configured to at least partially house the vibration part 110; and supporting parts 130SR, 130SL configured to support the vibration part 110 by coupling the vibration part 110 and the housing 120, wherein the supporting parts 130SR, 130SL are each configured to have a dynamic stiffness that amplifies or attenuates transmission of a vibration of at least a predetermined frequency in vibrations generated in at least one direction by the vibration part 110 in a state of holding the vibrating member, and a static stiffness required for supporting the vibration part 110 in the state of holding the vibrating member. A system including the structure 100 and the vibrating member has characteristics in which a vibration transmittance gradually decreases, as a vibration frequency of the vibration in the at least one direction increases, after exhibiting an excited vibration mode in which the vibration transmittance is increased. The supporting parts 130SR, 130SL have the dynamic stiffness that exhibits the excited vibration mode such that the vibration transmittance at the predetermined frequency is greater or smaller than 1.
